Hi All,
I'm offering N.G.V. + Turbine wheels blank kits for sale. Material is 304 stainless for the outer and inner shroud (.065" thick walls), 321 stainless .035" thick for the NGV blades (16 supplied, 15 needed) milled square. 347 stainless for the inner ring and 347 stainless .250" thick for the turbine blank. The outer ring that mounts to the outer case also provided. The turbine wheels have .312" holes bored, have been thickness machined per Kamps plans except I left a raised ring .125" for grinding for balance. The inner ring has been Dykem blued and scribed for the 65 degree entrance angle and 30 degree exit angle. The turbine blanks have been Dykem blued and scribed for 19 blades. Blade length will end up around .500". I also have a modular shaft tunnel which will need the flanges welded, but I've found it's easier to machine both bearing pockets using a small bore home type lathe (as long as your through hole spindle will accept 1.250" stock). I also have two smaller turbine disks one rough milled, no hole the other a Schreckling type wheel .125" thick. The three kits will have a finished turbine diameter of roughly 85, 87 and 89 mm.
I highly recommend you have an experienced TIG welder, do the welds. I also have to add a disclaimer similar to the Kingtech one, I, Jeff Pittel accepts no responsibility for any injury you incur for parts that I've machined. Prices below would not include shipping. I'll gladly accept returns, but you'd have to pay shipping. I've never shipped anything across the "ponds", it may be cost prohibitive. Prices in US dollars.
Pricing is:
85mm kit 250.00 (this kit has a welded stainless tubing 3.5" diameter outer shroud, which is not that concentric)
87mm kit 350.00
89mm kit 350.00
Shaft tunnel with flanges 150.00 (includes a bearing that is damaged, but suitable for machining the pockets to size)
Kamps turbine wheel blank 347 stainless .250 thick rough milled no hole 75.00
Schreckling turbine wheel blank 347 stainless .125" thick blade slot have been cut 75.00
I am located in the US/Michigan
Regards
